TO ALL 'WHOM I'l MAY CONCERN:

Y Bc it known thatI., WILLIM D. BAKER, of Marshfield, in the county of Plymouth, and State of liassachusetts, have invented a' new and improved Chain-Stopper and Windlass for ships and other vesselsyand that the .following description, taken in connection with the accompanying drawings hereinafter referred` to, forms a full and exact specification ofthe same, wherein I have set forth the nature andprinciples of my said improve. mentsgby which my invention may be distinguished from all others et' a similaiclas's,'together with such parts as I cla-im and desire tohave secured to me by Letters Patent.l i

This invention consists in arranginga plurality of drums and brakes in such a. manuel' that an anchor may be raised with facility and lowered withany` degree of speed, the lowering or dropping of the anchor being under the lperfect control of the operator. This invention is applicable as a windlass or chain-stopper, or both. In the accompanying sheet of drawingsi Figure l `is u side sectional view of my invention, taken in the line .fr fr, fig. 2. Figure 2, a plan or top view of the saine., Y Similar letters of reference indicate corresponding parts. A I A A A represent .three parallel shafts, which are placed in a suitable frame, B, and have each a. drum, C, on them, around all of which the anchor-chain D passes, said chain making one convolution around each drum, as shown clearly in fig. 2. Thesedrums are on one end of the shafts A, and on the opposite ends .pulleys E are placed and firmly keyed 'or secured.. These pulleys E have eaclra metallic strap, F, passing over them, and all of these straps are secured at one end to a shaft, G, which is provided with a' hole, a, to receive a handlever. The opposite ends of these metallic straps are secured to pins b, which are driven in the frame Blnear their respective pulleys E, each strap passing around its pulley so as to be in contact with the greater portion of' its periphery, as shown clearly in fig. 1. i Y,

It will be seen from the above description that by turning the shaft G, through the medium of the handlcver which is fitted in it, all the straps F will be' made to bind or hear upon the peripheriesof all the pulleys, as all of the straps are attachedlat one end to the4 shaft G. Hence the speed of thedescent of 'the anchor may be regulated as desired, owing to thc great amount of friction which may be'b'rought to bear upon thc periphcries'of the pulleys E; it being sufficient, if necessary, to hold the4 anchor in asuspended state. By having the shafts- A connected by gears so that `all may `be turned by theA application oi' power to any one of them, thev device may be used as arwindlass. .When used as a chain-stopper only, the anchorchain D passes from the windlass around the drums C, as shown, the device being placed on the vessel between the windlass and the lhawse-ho`les; 'g i Having thus described my invention, I claim as new, and desire te secure by-'Letters Patent Aships windlass or chain-stopper, or both,`composed of plurality of shafts A,'provided with drums C and pulleys E, with metallic straps F applied to them, and all connected at one end to a single shaft, G, substantially as shown and described.-
